I need a replacement central heating domestic pump. Present on is a series 4, UK7509, 4.35/130 type what is the latest equivelent pump?

Circulating pumps have undergone a lot of energy efficiency changes recently.

If you currently have a 35/130 standard domestic circulating pump, it would probably suit a Grundfos Alpha 2 15-50 130.

The Grundfos ALPHA2 L is an advanced energy efficient domestic circulator that meets EuP legislative requirements.

This makes it an ideal choice for a variety of domestic circulation heating systems. But I do advise talking to a heating engineer to ensure the changes wont affect your set up.
